About Four Audio System Software

The Four Audio System Software can be used to create loudspeaker settings with FIR filtering for our PPA series, PR4-DSP and HD2 units. Developers can create presets and assign rights to End Users, e.g. to use room EQs or change gain and delay. End Users use the Controller view to change these settings according to their needs.
